Reason for

?

1.Special Theory of Relativity (STR) shows space to be much like time
?
Think about whether this reason is strong or weak
2.Objects extend in space by having spatial parts

Think about whether this reason is strong or weak

Reasons Against

2 perspectives

Reason against 1 of 2

?

1.STR is compatible with endurantism if objects persist by being wholly present at each relativistic frame-relative hyperplane of simultaneity.
?
Think about whether this reason is strong or weak
2.The analogy between space and time breaks down because spatial extension is simultaneous whereas temporal extension is not, making 'having a part at t' fundamentally unlike 'having a part at location l'.
?
Think about whether this reason is strong or weak

Reason against 2 of 2

?

1.Temporal parts entail that there are distinct, momentary entities bearing properties like 'being in pain,' yet our best psychological and moral practices attribute suffering to persisting persons, not instantaneous stages.
?
Think about whether this reason is strong or weak
2.If perdurantism is true, personal identity over time reduces to relations between stages, but Chisholm and van Inwagen argue no such purely relational account can ground the strict numerical identity that rationality and moral responsibility require.
?
Think about whether this reason is strong or weak

A first argument from STR to perdurantism goes as follows: STR shows space to be much like time, objects extend in space by having spatial parts, so objects persist through time by having temporal parts. But this argument is weak: although STR does show space to be like time in some respects, the theory does still differentiate between spatial and temporal dimensions. Even if it did not, we would need some further reason to believe that persistence must be just like spatial extension.
